To all whom it may concern: p

Be it known that we, JAMns M. WASSON and MICHAEL E. GAHN, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Apparatus for Lifting system, the

Liquids; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in apparatus for lifting liquids, especially for lifting water, oil, or other liquids from wells.

It is quite common in wells that the liquid will rise to a considerable height inside the well casing, but has to be lifted through a comparatively short distance to the surface of the ground, or to the point of distribution. This additional lift is accomplished in a variety of ways, such as by force pumps, air jets,.or the like, and our invention is in'tended to provide an improvement on the apparatus by means of which the liquid is lifted Artesian or oil through the use of an air jet, or a series ofair jets.

Our invention will be more clearly understood after reference to the accompanying drawings, in which the same-parts are indicated by the same reference symbols throughout the several views, and in which Figure 1 shows a casing, and shows the paratus in elevation, sor shown diagrammatically;

It may also be provided with a quently Fig. 3 is a section alongv the line 33 of Fig. 1, parts being shown on one of the air nozzles as de- .of internally screw-threaded openings f which are preferably arranged in the staggered relation as shown in Figs. 1, 2 and 3. Into these screw-threaded openings f the necks g of the nozzles G are screwed, which nozzles are preferably provided with expanding chambers g, and covered with the cap H provided with a series of apertures 72. therein, as shown most clearly in Figs. 4 and 5. These nozzles are arranged as shown in Fig. 3 to impart a vortical direction to the air currents issuing therefrom, and conseto create a whirl the water for purposes hereinafter described. Compressed air may be supplied to the air compressor in any convenient way, or storage flasks may be used if desired. The location of the section F of the'air pipe should preferably be about three times as far below the static head of liquid in the well as the static head of liquid in the well is below the delivery pipe C, so that the apparatus will operate efficiently; although under certain conditions it may be more advantageous to locate the nozzles at a still lower comparative depth.

The operation of the device is as follows: Air under pressure being contained in the air compressor. the valve f is opened, turning the air pressure on the pipe F, and the valve 0 is opened to permit the escape of the liquid as it rises rushing down through the pipe F will enter the nozzle section F and, escaping into the nozzles G, will extend into the chamber 9 and will pass through the series of openings h in the cap H, and will enter the liquid in 'a series of finely distributed streams of air,-and at a tangent to the circle formed by said nozzle outlets. Moreover, theair being under compression will tend to force the liquid upward, as well as to lift the same owing to its lesser specific gravity,

and the spiral motion of the'air andliquid pipe F, controlled by the p in the well casing. Air

escaping upwardly through the liquid without exerclsing an adequate lifting effect materially weakened as would be the case if static head of the liquid in the perforations were horizontal plane.

The length of the pipe section 'F and the number and disposition of the nozzles G may be varied to suit varying requirements of the apparatus, and this pipe section F may be raised or lowered relative to the the well, according to the-special conditions. It will be obvious that various modifications might be made in our device, and in the construction, combination and arrangement of the parts constituting the same which might be used .without departing from the spirit, of our invention.

Having thus described our invention what we claim and desire to secure by Letters Patent of the United States is 1. Apparatus for lifting liquids, comprising a cylindrical casing, j ectin'g down into said cylindrical casing and provided with a series of tangentially disposed curved expanding nozzles projecting therefrom, and means for supplying compressed air to said air pipe, substantially as described.
